BRS Felt Filter Sock with Draw String

Quick Overview

Filter Socks are used on overflows to remove small floating particles from aquarium water. This can dramatically improve water quality and reduce maintenance on filters that would otherwise become clogged.

Felt Filter Sock is better at removing particles than mesh but can clog faster. Draw string attaches directly to plumbing.

Great quality, very thick and heavy, will last long if power wash to clean, seemed to be able to keep in sump a couple extra days compared to other socks

These are a quality product and do catch everything but after trying I found that my systems works better with the mesh version.

Much thicker than expected. Catches even the smallest particle. My tank looks so much better. Just change them out every couple of days, clean them and you are back in business.

Bought 5 of these to try on my reef tank and WOW! They capture everything and now I can't imagine not using them. I bought another 5 to have on hand so I can swap them out frequently.

These socks are fantastic. They capture *everything*. I turn them inside out, toss them in my washer, and *boom* clean sock ready to re-use.

I wasn't running socks for awhile, and decided to try out socks. Seems like tank is cleaner and skimmer is working a lot less. (heavy stuff being caught in socks letting skimmer work on anything that doesn't get caught in sock). I have 8 or 9 socks, and wash them weekly.
